Segate EXOS Drives 7/18/2020 11:29:37 AM

Pros: EXOS discs are a SYSTEM ADMIN's DREAM!
LONG lasting (MTBF), Exceptional data throughput for SATA (much higher with SAS), super warranty and energy efficient.
Built for ENTERPRISE level reliability in demanding production data environments like: Transactional Databases, Email Servers, NAS/SAN Storage, Application Servers, Surveillance Storage Servers and Domain Controllers.
Despite their cost they also are great for high demand workstations.
Disc level encryption on selected models makes disc retirement easier and more secure.

Cons: Not enough System Admin's take the time to get on these forums and relate their 'real-world' experiences with these products.

Overall Review: I hope this review is helpful to anyone looking at this line of drives and worried about some of the posted reviews related to experience/reliability.

I have several hundred of the Seagate EXOS series drives from 1Tib to 14Tib deployed on production systems which I own, rent or administer - in all types of environments from climate controlled datacenter deployments to hot and dirty network closets in industrial environments.

These products shine in Mission Critical NAS/SAN Storage, High availability Transactional Databases, Corporate Video Surveillance Storage Systems, Web Server Clusters and Email Server Clusters. I also deploy them in high powered workstations where endurance is necessary and/or desired.
All of this endurance/reliability does not mean these drives are not at ease in the average home computer because they work great in an 'everyday' application if you don't mind the cost of entry. The workstation where I am writing this review has a pair of 1Tib Segate Enterprise drives in RAID 1 which have been happily spinning along for 5+ years.

The bottom line is this: if your data or the data of your clients is important, these discs are an exceptional choice for reliability and high ROI (return on investment).

I see reviews complaining about disc failures related to the EXOS/Enterprise line, I can confidently pass on that I have experienced no such problem with this line of drives. I have NEVER had an EXOS/Enterprise drive come DOA. This doesn't mean that DOA drives don't show up, I have simply never experienced this issue. Again, these drives are targeted for ENTERPRISE level storage systems - they can and do fail like any equipment. That being said, Seagate has NEVER failed to Warranty a failed disc (within the warranty period) from the systems within my responsibility. The difference here might be - ENTERPRISE users keep backup drives on site and in stock for immediate replacement when eventual failures occur so this generally does not become a game ending issue and warranty processing wait times are non-critical.

As a service to people looking at this line of drives I checked the average age of my running drives and 65% of the deployed stock has been installed in production environments for 5+ years (approximately 250 drives). I have not had an EXOS disc failure in 235 days (as of this review).

I generally purchase some of my discs directly from NEWEGG when the prices are right. Never a warranty issue related to direct purchase from a Seagate authorized reseller.

MY CONCLUSION/OPINION: This is an exceptional line of ENTERPRISE level products with a good warranty and superb return on investment.

Purchased six drives 12/30/2019 6:52:10 PM

Pros: Drives were well packaged for shipping
Long 5 year warranty, if valid.

Cons: I checked the warranty status of the drives (while they were still in the sealed anti-static package) with Seagate's online warranty validation page and two of the six drives are not covered by warranty, they were listed as Component*
I purchased these drives directly from NewEgg not a marketplace partner. Looks I was shipped used equipment.
Listed below is Seagate's details:

Component
The product you identified was sold as a system component. Please contact your place of purchase for service. Seagate sells many drives to direct OEM (Original Equipment Manufacturer) customers. These products are usually configured for the OEMs only, as components for their systems. You must contact your place of purchase for any warranty support on these drives.

Overall Review: I hope others reading this review have a better experience

Not enterprise quality for me 10/17/2019 9:51:49 AM

Pros: Nothing

Cons: Bad sectors

Overall Review: I purchased this drive twice and both arrived with over 2.1 million KB of bad sectors. Regardless of what articles on line say, using the /f and /r switches will NOT repair bad sectors on HDDs. I sent both back to Platinum Micro for a full refund. Platinum Micro was easy to work with.

Be Careful 5/26/2019 8:23:41 AM

Pros: THIS DRIVE IS ENCRYPTED!
Not For Use In Home Computers!

Cons: SEAGATE WILL NOT DISCLOSE THE ENCRYPTION SECRETS.
IT IS TO BE USED IN ENTERPRISE & DATA CENTER SYSTEMS ONLY.
Use Barracuda or IronWolf Drives in NON ENTERPRISE SYSTEMS!!!

Overall Review: Excellent Customer Service From SEAGATE & NEWEGG.
BRAVO GUY'S, BRAVO!!!

They work and they keep getting cheaper 5/18/2019 10:06:21 AM

Pros: Rock Solid traditional hard drive with nice size cache and good response times.

Cons: Prices are dropping monthly...can get 8GB for same price 3 months later ;-)

Overall Review: With all the SSD tech, I wonder why I am purchasing traditional hard drives...My latest system has both SSD and traditional HDs. I am using the traditional HDs for backups...

Works in Linux (Believe it or not) 1/28/2019 10:46:11 AM

Pros: Was able to make a full 4tb partition using Ubuntu 18.04. (link below for guide)
Size + Price + Enterprise = good buy

Cons: Maybe speed? Read below for more details.

Overall Review: I'm using this drive for my Home Network as backup and Storage. It is not in RAID and not in a NAS. There are probably bottle-necks everywhere in my setup. Because of that, transfer speeds have been slow. But the drive when transferring files from one Drive to another on the same computer seems to have good speed. It's not a requirement that I have fast transfer speeds so it's serving it's purpose.
